[AST] Match the FoldingSetNodeID computed before and after creating TypedefType (#157662) At some point the call to static `TypedefType::Profile` inside `ASTContext::getTypedefType` got out-of-sync with the non-static `TypedefType::Profile`. This seem to cause some bad performance patterns with `FoldingSet` and are seeing 10x increases in compile times in certain scenarios. After this commit, the compile times go back to normal. This commit does not include tests or benchmarks because we want to land this ASAP to unbreak our deployment. I will work on adding asserts, tests or benchmarks in a follow-up.
Welcome to the LLVM project!
This repository contains the source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and run-time environments.
The LLVM project has multiple components. The core of the project is itself called “LLVM”. This contains all of the tools, libraries, and header files needed to process intermediate representations and convert them into object files. Tools include an assembler, disassembler, bitcode analyzer, and bitcode optimizer.
C-like languages use the Clang frontend. This component compiles C, C++, Objective-C, and Objective-C++ code into LLVM bitcode -- and from there into object files, using LLVM.
Other components include: the libc++ C++ standard library, the LLD linker, and more.
Consult the Getting Started with LLVM page for information on building and running LLVM.
